1
Stand with feet hip-width apart, barefoot on the ground with neutral spine and upright posture. Keep your core engaged throughout the movement.
2
Bring both hands to chest height with palms facing inward, elbows bent at approximately 90 degrees. Position hands at chest level in preparation for the clapping motion.
3
Extend arms outward and slightly upward, opening the chest while maintaining control. Elbows remain slightly bent to prevent hyperextension. This is the eccentric lengthening phase where pectoralis major is stretched.
4
Explosively drive hands together across the midline of the body with a clapping motion, bringing palms together in front of the chest. Return to starting position with hands at chest level with control. The pectoralis major contracts concentrically during this phase.
